An ophthalmic patient unit is a specialized area in a hospital for eye surgery, featuring consultation rooms, diagnostic labs (OCT, fundus cameras), minor procedure rooms (lasers, injections), sterile operating theaters for complex surgeries (cataracts, retinal), and recovery bays for post-op care, all designed for patient comfort and safety, often including adjustable operating tables and focus on infection control to handle delicate eye procedures like LASIK, vitrectomies, and glaucoma surgery.
